APOLLO 16

Apollo 16 Training-Used Lunar Rover Terrain and Navigation
Compass. An interesting two-sided device made of coated
cardstock, overall 8" x 10.5", with an 8" diameter rotatable dial
marked in degrees mounted on the front with a grommet along with a
flip-up sight guide. Instructions at the front top read: "BEARING
DETERMINATION/ 1. Line pointer on target/ 2. Level compass/ 3. Set
shadow angle/ 4. Read target bearing (3 readings)" and "RETURN TO
LM/ 1. Set pointer to LM Bearing/ 2. Level compass/ 3. Rotate
compass ass'y to shadow angle/ 4. Note features along LM bearing
line". Handwritten beneath is "Descartes/ Apollo 16". The
printing date is given as January 14, 1972. This was used to plan a
traverse away from the lunar module and to safely return as
direction and distance are difficult to determine on the moon by
the naked eye. The verso has a "Nominal Shadow Data (April)" chart.
A rare item.
